The Prince of Wales formally opened a Jubilee show garden during the East of England Show in Peterborough.
The garden was designed and constructed by John Farley of bagged aggregates specialists Aggbag.
It was presented to the prince by Julie Boyce, southern area business manager for aggregates at Lafarge which donated much of the hard landscaping for the temporary installation from its Dry Rigg quarry in North Yorkshire which supplies Aggbag.
"I wanted to create an illusion of time by combining hard and soft landscaping in a totally different way," said Mr Farley. "To do this, I used one of the oldest rocks to be quarried in Britain, a dark grey, almost black gritstone that comes from Dry Rigg."
The stone was complemented in the installation by six concentric circles radiating out from the feature rock to represent the six decades of the Queen's reign
The garden was constructed in partnership with by Bettaland of Crowland, with Shaun Dring responsible for the planting design
It will be moved to a permanent site at the Queen's Norfolk estate on 25th July during the Royal Sandringham Show.
